MFGTool For i.MX Boards

MFGTool is the NXP® tool to deploy images to an i.MX-based board. LmP provides two scripts to deploy the build artifacts using this tool:

  • bootloader.uuu: used to deploy SPL and U-Boot FIT image (u-boot.itb)
  • full_image.uuu: used to deploy the entire image, from SPL to rootfs

This support can be extended to support other features, such as fusing and closing a board for secure boot. Note that this case is not covered in this document.

The mfgtool-files package is built by the CI when the mfg_tools node is included in factory-config.yml Factory Definition. It is built locally when DISTRO=lmp-mfgtool is set.

To enable a custom mfgtool-files package, you must provide the following configuration:

  • U-Boot: you to provide a configuration file (lmp.cfg) to be used for the mfgtool-files U-Boot build (u-boot-fio-mfgtool). This is similar to the configuration file used by DISTRO=lmp, but should include SDP, USB and fastboot support.
  • OP-TEE: Same for the standard u-boot-fio support. You need to provide machine-specific configuration to OP-TEE for the mfgtool-files building (optee-os-fio-mfgtool). This includes OP-TEE machine name, UART address, and overlay address.
  • mfgtool-files: The bootloader.uuu.in and full_image.uuu.in input files to generate the MFGTool scripts. You can provide the same files as the reference board support in LmP.
